Answer 1

You will need 2 pear packages

1. PHP-ExcelReader package
2. Spreadsheet_Excel_Writer package

What you need to do is read first the excel file use PHP-ExcelReader package It reads the binary format of XLS files directly and can return values and formats from any cell. http://code.google.com/p/php-excel-reader/

read the excel file

$data = new Spreadsheet_Excel_Reader("test.xls");

show the data of the file

$data->dump($row_numbers=false,$col_letters=false,$sheet=0,$table_class='excel')

---

Once you have stored the data in a variable save the data in another file this time you will use the The Spreadsheet_Excel_Writer package http://pear.php.net/package/Spreadsheet_Excel_Writer

 <?php
require_once 'Spreadsheet/Excel/Writer.php';
$workbook = new Spreadsheet_Excel_Writer('test.xls');
$worksheet =& $workbook->addWorksheet('My first worksheet');
if (PEAR::isError($worksheet)) {
    die($worksheet->getMessage());
}
$workbook->close();
?>
